You can process the template and then save the resulting page wherever you want. Either giving it default values or not. Consider:

use Template;

my $template = Template->new({
    INCLUDE_PATH => $template_path,
}) || die $!;

my %vars = ();
my $pre_processed_template = '';

# this will get you the processed template
$template->process('master_template.html', \%vars, \$pre_processed_tem
+plate);

# now you can save the processed page with the contents of $pre_proces
+sed_template.
